The invention discloses lightweight aggregate concrete, and relates to the technical field of building materials. The lightweight aggregate concrete is prepared from the following raw materials in parts by weight: 200 to 300 parts of cement, 150 to 180 parts of water, 50 to 80 parts of fly ash, 20 to 60 parts of lightweight aggregate and 5 to 8 parts of polycarboxylic acid type water reducing agent. Meanwhile, a preparation method of the lightweight aggregate concrete comprises the following steps: (1) preparing the cement, the water, the fly ash, the lightweight aggregate and the polycarboxylic acid water reducer; (2) transferring the raw materials in the step (1) into a stirrer, stirring and mixing, and pouring into a mold; and (3) curing the concrete in the mold in the step (2). The modified ceramsite and the modified kaolin in the lightweight aggregate play key roles, and the prepared concrete has excellent performance parameters such as apparent density, compressive strength, breaking strength and heat conductivity coefficient, and is high-quality lightweight aggregate concrete.
本发明公开了一种轻骨料混凝土，涉及建筑材料技术领域。所述的轻骨料混凝土，包括以下原料：水泥：200份‑300份，水：150份‑180份，粉煤灰：50份‑80份，轻骨料：20份‑60份，聚羧酸系减水剂：5份‑8份；同时，上述轻骨料混凝土的制备方法如下：(1)准备水泥、水、粉煤灰、轻骨料、聚羧酸系减水剂；(2)步骤(1)中各原料转移到搅拌机中进行搅拌混合，并倒入模具中；(3)对步骤(2)模具中的混凝土进行养护。轻骨料中改性陶粒、改性高岭土起到关键性作用，制备的混凝土，在表观密度、抗压强度、抗折强度及导热系数等性能参数上表现优异，为优质的轻骨料混凝土。
